BALEIOR, PACKAGE, REMOVING MECHANISM.

Louisiana, have (invented certain new and useful Improvements in Bale or 1 Package Removing Mechanism; andI do hereby (1'81 .clare the following to. be a full, clear, and

exact description ofth e invention, such as will enable others skilled in the art to which it appertains tomake and use the same,

The invention relates to mechanism for extracting, withdrawing or removing indi vidual elements, such as bales,packages or other containers of goods inbulk, or 'se'parate articles, which it is customary to as semble and store in rows and tiers, ,and to this-end, comprises aframeadaptedtobe brought into proximity with the face of the pile 0f bales orqthe like, associated with lifting jack mechanism adapted :to engage,

and lift the, bales -;superposed on the bale to be extracted, togethervwithmeans wh ch may conveniently; take the-form of long hooks or rods adaptedgto be passed beacln As illustratedin Fig. 1, the extensitween the bale to be extracted and theiadjacent bales, and to engage the rear of the desired bale, and suitable means, preferably a winding drumand cable oonnectedwith theghooks or other bale-engaging element to exercise a longitudinalpull ,onthe hooksw and thereby Withdraw the desired bale, after i the latter hasbeen relieved of the weight mounted upon awertica-lly adjustable tower-,

companying drawing, in which,

of the superposed bales bythe lifting jack mechanism to an extent suflicient tofpermit such withdrawal.

2 and suitably strengthened at the Various angles and corners by gusset plates. Connecting the upper rear portions-.ofthe side frames, 1 is an angle bar 8, the horizontal fiangeof which is adapted to be forced be- 6 tween the bales of superposed rows, as in-,

, dicated in Fig. 1, when the frame is brought pile on stack of bales. I

In orderto support the frame in proper ,6 relation in front of the stack of bales, there is provided a longitudinally adjustable extensiblelifting jack mechanism oneach side of the frame, as shown in Fig, ,Eachof said lifting jack mechanisms comprises a 7 strut member 4, preferably made up of readily removable pipe or red sections, con nested to each of the cross braces 2 of the frame by means ofv a pivoted lug 7 adapted into abutting relation with the face of the .to be inserted inithe end of the upper tu- 7 bnlar section of the strut hand a jack 5 I connected with the lower end of the strut resting upon a base plate 6, Thesaid jack; 5 maybe of any desired or convenient type and is illustrated as a simple form of screw '3 superposed on thebale to be extracted to relievethe latter ofthe weight ofthe upper .bales.

Thelength of the struts tmay be regulated by inserting or removing-the intermediate sections so as to properly sup- 9 portthe frame immediately in front of the bale to be removed, as will be readily under- Journaled in suitable bearings on the upi I per member of each of the sideframes is 7,9

W 7 Each of said drum sect ons lsprovided with a section of haulmg cable 20, and the cable sections pass'over guide pane /s17, 17' mounted upon a 'trans- '1 a differential gearing 11,'as illustrated" in 155 chine is simple,compactand relatively'light and may be readily-moved from place verse shaft 18 journaledin the forward-ends of the frame membersl. The end of each of the cables 20 is'connected with a hook 21.

The" said hooks 21, are adapted to bepas'sed along each side of the bale to be extracted between the same and the adjacent bales, until the rear ends thereof project beyond the rearface of the stack of bales, after which the hooks are turned so as to cause the hooked ends thereof to engage the rear face of the bale to be extracted, as illustrated in Fig; 1. r If desired, mechanism may be supported by means of cables or the like from an overhead crane-or traveling trolley, the cables being connected to the frame by means ofeye bolts 25, 25, as indicated in Fig.1. a

In operating the apparatus to extract or withdraw a bale from a pile, the frame is moved to a position immediately in front of the'desired'bale and 'until the rear face of the frame abuts the face'of the pile, with thetransverse member3 of the frame underlying the forward edges of the bales immediately above the bale to be extracted. The strut members 4 of the lifting jack mechanism'are then adjusted as to length to sup port the framefrom the floor or other foundation, and the lifting jacks 5 are operated to elevate the struts 1 and thereby lift the superposed bales. Thej-cable sections 20 having been drawn oh the drums to a suflicient extent to permit the long hooks 21 being passedalong each side of the desired bale until the hook ends thereof engage the rear face ofthe desired bale, the drums 10' are then operated by means of the hand levers 14 to wind upthecable'sections. By

reason of the differential gearing interposed j between ithedrum 'sections, equal and uniremoved and transported. to extract another bale.

form pulling strains are imposed upon the two cable sections 20. As the cable sections are wound upon the corresponding drums,

' the hooks and the bale engaged thereby are moved transversely'of the pile, until the de sired bale either drops out or may be quickly forced out of engagement with the other After the bale has been removed, the

bales. jacks 5 are reversed to permit the superposed ;balesto settle down into their normal position, after which the *mechanism can be a position 'to 1 .5 will be particularly noted that a. m:

The said modification involves a frame consisting of the side members 1, 1 front cross brace 1", arear cross vbrace 3 terminating in two horizontal baleengaging flange members 3", which correspond with-the bale liftingelement 3 of the modification shown in Figs. 1 .and 2, The rear portion of the frame also includes in clined brace members 2, and a horizontal' cross connection 2 which is provided with a central socket to receive the end of the adjustable and extensible strut 4, which, together wlth the lifting jack5 constitutes the means for raising the bales superposed onthe one to be extracted, as hereinbefore described. Journaled in the forward'part of the frame side members 1 is a shaft 12 carrying a winding drum 10"; upon which:

"operates :hauling cable 20 attached to a cross yoke 20, to the outer ends of'which' are secured rods or hooks 21 which are adapted tobe passed through the stack of bales along eachside of the balelto be removed and to engage the rear faceof said bale by -means of the hooks o'n-lthe ends thereof, or, if desired, a sling-like connection 22, asillustrated in Fig. 4:. The drum 10 is operated bymeans of a pinion 13 on i one end-of the shaft thereof,which meshes" with a ratchet gear l3" journaled onthe end of a stub shaft; secured to the side frame 1, which ratchet gear is operated by a pawl 15 carried by a hand lever 14 loosely mounted on the stub shaft. lock-- ing pawl16 mounted on the side frame 1' preferably engages the'pinion 13,"as shown in F ig. 3.
